- August_Beer abstract "August Beer (German: [beːɐ̯]; 31 July 1825 – 18 November 1863) was a German physicist, chemist, and mathematician. Beer was born in Trier, where he studied mathematics and natural sciences. Beer was educated at the technical school and gymnasium of his native town until 1845, when he went to Bonn to study mathematics and the sciences under the mathematician and physicist Julius Plücker, whose assistant he became later. In 1848 he won the prize for his essay, \"De Situ Axium Opticorum in Crystallis Biaxibus,\" and obtained the degree of Ph.D. Two years later he was appointed lecturer at the University of Bonn.In 1852, Beer published a paper on the absorption of red light in coloured aqueous solutions of various salts. Beer makes use of the fact, derived from Bouguer’s and Lambert’s absorption laws, that the intensity of light transmitted through a solution at a given wavelength decreases exponentially with the path length d and the concentration c of the solute (the solvent is considered non-absorbing). Actually, the “Absorption Coëfficient” defined by Beer in his paper is the transmittance (or transmission ratio), T = I / I0. Thus, as pointed out by Beer, the transmittance of a concentrated solution can be derived from a measurement of the transmittance of a dilute solution (Beer, 1852).Indeed, the transmittance measured for any concentration and path length can be normalized to the corresponding transmittance for a standard concentration and path length. Beer in a number of experiments confirms this, defining a standard concentration of 10%, and a standard path length of 10 cm. The photometer, devised by Beer, is shown in the gallery below.Beer continued to publishing the results of his scientific labors, writing in 1854 Einleitung in die höhere Optik (Introduction to the Higher Optical). His findings, together with those of Johann Heinrich Lambert, make up the Beer–Lambert law. In 1855 he was appointed professor of mathematics at the University of Bonn. Beer also wrote \"Einheit in der Electrostatik,\" published two years after his death. He died in Bonn in 1863.".
